question for welders

I took a welding class at a local community college just for grins. I hadn't done a lot of welding in a long time. I got to play with their Miller TIG welders. I liked the Synchrowave 250DX ones the best. I had pretty good luck with the new inverter welders. They seemed to weld nice, but sure were noisy compared to the DX. Anyways, I was grinding the tungsten by rolling it in my fingers against the wheel (horizontal). They said that can cause the arc to be unstable. They said to grind towards the tip (vertical) to make the lines of grinding along the centerline of the tungsten. I think they also said the 2% thoriated was out, now they have some other elements to make the start easier without the health issues. I think the pure tungsten had some problems too. This website was recommended by the instructor.
